SPECIFICATION forming part of Letters Patent No.760,'861, dated May 24, 1904. Application filed FebruafyflZ, 1904:. SeriallIo. 193,27. (N model.) a

To all whom, it may concern;

and J AMES M. GAUME, citizens of the United States, residing at Danville, in the county of Harper and State of Kansas, have invented cer- 1 automatic weighing-machines, the objects of which are, first, to provide an automatlc;

weighing-machine which shall automatically receive, weigh, and discharge in. amountsof predetermined weight substances generally of a granular nature-such as sand, coal, &c., and grains, millstuifs, and the l ke with speed and accuracy; second, to so construct machine which shall be cheap in cost of manufacture, reliablein its operation, very durable, and not at all liable to get out of order. We attain these objects by the mechanism illustratedin the accompanying drawings, in,

but differently-formed parts.

' In the preferred form of our invention Fig. 4 is a side elevation of certain equivalent I (seen in Figs. 1 2 3)a shaft 1 rotates in bear-' ings 2 on frame 3.and carries two annular disks or end pieces 4,connected by fixed partitions 5, 6, and 7, subdividing the space be; tween disks .4 into three rotatable compartments or bins 8, 9, and 10. Each of said bins is provided with a rotatably-attached outer end 8, 9, and 10, respectively, of suitable length to rotate on rods 8 9 and 1Q", respectively, to form sloping end gates, each for its respective bin, as seen at 8, 9, and 10 in Fig. 1, and the free edge of each end gate by the successive rotations of its bin will be brought into and gravitate to the position seen at 9 in Fig. 1. Should centrifugal force cause 7 1 free edges of end gates 8, 9, and 10f. to ro- Be it known that we, FREDERICK M. GAUME tate outward, said edges will be stopped by their respective abutments 11, 12, and 13. (Seen in Figs. 1 and 2.) Shaft lcarriesupon its extremities the two triangular shaped cams 1 1 and 15, having apexes 1 1, 1d", and In Fig. 1 is seen one of two members 17, provided with a preferably hardened and polished surface plate '16, resting upon apeXes 1 1 and 14?. Said two members 17 uniteand arej formed with a graduated scale-beam 17, carrying weight 18, adjustably secured along said'beam at any desiredpoint by set-screw 19.

Cover 20 is provided with hopper 21, into which inthe operation of my invention gravitates the substance 22 which is being weighed, as seen in Fig. 1. When the proper weight of substance 22, as indicated by weight 18 on beam 17*, has gravitated from hopper 21 into bin 8, the gravity of substance 22 will cause bins 8, 9, and 10 to rotate, driving shaft 1, carrying triangular cams 14: and 15 and their apexes 1 1, 1 1 andv 14: and by said rotation of apeXes beneath members 17 cause members 17, scale-beam 17, and weight 18 to be lifted to the position seen in Fig. 8, and the further rotation of bins and attached parts will allow weight 18 and its attached parts to gravitate to the position seen in Fig. 1. It will be seen by referring to Fig. 1. that by the beforedescribed rotation of bins 8, 9, and 10 partition 7 and vertically-suspended end gate 9 will rotate past. and beneath hopper 21 until they have by gravity been caused to occupy the respective positions of bin 8 and end gate 8, and it will be further seen and understood thatthe narrow edge of partition 7 passing beneath hopper 21, will quickly and accurately bring bin 9 in position to receive substance 22 from hopper 21 and that the vertically-suspended end gate 9 will neither defleet nor retard substance 22 from entering bin 9. Thebefore-described rotationof bins 8, 9, and'lO will continue so long as substance 22 is supplied to hopper 21, and after being weighed substance 22 will gravitate from bins 8, 9, and 10 (in succession) through dischargespout 23, as seen in Fig. 3. A cord or rod 17 is attached to member 17 for the operation of any ordinary tally-box. (Not shown.)

I'Vhile we have shown and described our invention as having a hopper 21, cover 20, and a discharge-spout 23, it is evident that such parts could be omitted where circumstances do not require them ..without impairing the operation of our invention, and we reserve the right so to do.

here frictional wear upon face-plate 16 and apexes 14c 14: lt is excessive, owing to excessive weight of quantities of substance 22, shaft 25, bearing-plates 26, friction-rolls 26, 26 and 26, actuating one or more members 27 of a scale-beam 27, pivotal at 27 and provided with a weight 28 and set-screw 29,

as seen in Fig. 4C, are used as equivalents to shaft 1, cam 14, apexes 14E 1 .1: 143, members 17 scale-beam 17, pivotal attachment .17, weight 18, and set-screw 19, as seen in Figs. 1 and 3, in the order given, and we further reserve the right to use any antifrictional bearings or to so modify the relative arrangement of parts as to comply with the various situations in which our invention may be used without departing from the spirit of our invention.

WV e are aware that automatic weighingmachines are in use in which a series of rotating bins actuate a weighted lever or scalebeam by gravity of substance being weighed therein, and therefore do not broadly claim such as being our invention; but all such inventions of which we are aware are either controlled by fragile or complicated parts liable to get out of order or have the outer ends of their rotating bins open, leaving substance weighed thereby to press outwardly against the inner surface of a box or casing inclosing them (not shown) and in which the various adhesive tendencies of said substances to the inner surface of said box and the lodgment and binding of small particles of substance between said box and the edges of the annular ends of said open bins act as irregular resistances to the rotation of said bins, thereby causing irregular and inaccurate weighing; but we are not aware that automatic weighing-machines have ever been known or used prior to our invention hereof in which substance being weighed rests solely against the inner surface of one ofa series of rotating bins unretarded by frictional contact of substance weighed with any fixed partsuch as the cover, casing, or discharge-spoutexcept where burdened with fragile or complicated parts liable to get out of order, as hereinbefore stated.

Therefore what we claim as new, and desire to secure by Letters Patent, is

1. In an automatic weighing-machine, the

combination with a series of rotatable bins, having fixed partitions extending between said bins to the limits thereof, of one end gate in each bin, each end gate being so pivotally attached to the sides of its bin as to operate by gravity in the manner and for the purposes specified.

2. In an automatic weighing-machine, three bins, in one annular series, mounted upon a rotatable shaft, having fixed bearings and supports, and carrying rigidly secured upon the extremities of said shaft, one or more triangular cams, each cam having three outward projections or apexes, acting in conjunction with a surface-plated member of a weighted lever or scale-beam for operatively holding and releasing said bins, as specified.

3. In an automatic weighing-machine, a series of three rotatable bins, having fixed partitions extending between said bins, to the limits thereof; each bin having one end gate pivotally attached at its upper edge to the sides of its bin and oscillatable therein; the whole being secured upon a rotatable shaft, having fixed bearings and supports, and provided with one or more triangular cams, each cam having three apexes; in combination with a weighted lever or scale-beam having a surface-plated member normally resting upon two of said apexes, and means for rotating said bins, shaft and cam as specified.

4:. In an automatic weighing-machine the combination with a series of three rotatable bins, having fixed partitions extending between said bins, to the limitsthereof, and a pivotally-attached end gate in each of said bins, a triangular cam and a weighted lever for operatively holding and releasing said bins; of a cover and a hopper above, and of a discharge-spout beneath said bins, as shown and specified.

5. In an automatic weighing-machine, a series of three rotatable bins, having fixed partitions extending between said bins, to the limits thereof and a pivotally-attaehed end gate in each of said bins, the whole, operatively rotated by gravity of substance being weighed, and having a triangular cam, and an adjustably-weighted lever or scale-beam, one or more members of which is provided with means for operating any ordinary tallybox.

In testimony whereof we affix our signatures in presence of two witnesses.
